put my first sr red top in my s13 and it runs......OK. its been running "ok" 4 about 2 weeks. "ok" isnt good enough 4 me. builds boost and pulls til boost is done building. once it hits 14psi it goes down to like 10psi. sometimes it goes to like 17psi and goes back down. newayz, it quits pulling after boost is built, its sluggish, it sux. vaccum read +-0 at idle and as i give it a lil tap of throttle it goes down to like -5 or so. shouldnt it be like -20 at idle? does this mean vaccum leak. bov is set tight. hks wastegate actuator, timing is dead nutz, fmic, all wiring is correct. ive done boosted cars b4 but never a factory turbo car so any help is much appreciated. thnx
